Due to the fact that so many people are get inconsistent results with their adapters we should gather together information to compare and see if we can find a common cause.
Here's mine.

i some how lost the use of my USB port after using the MHL to HDMI
however it still works as HDMI out, even after i flashed a new ROM and wiped everything, it's stuck in MHL to HDMI mode,
i can still charge my G'note via USB, and view in HDMI, but is no longer detected by Windows or Linux as a mass storage or Odin
Settings, unable to get to work
I have a Galaxy Nexus. Tried both stock and a custom 4.0.3 build that I did myself. Official Samsung MHL Adapter. Tried with airplane on and off, USB debugging on and off.
But no matter what, the display constantly flickers. If there is movement on the screen, then the flickering is reduced. And if there is no movement, the the screen goes off. So normal desktop is outputted as black. With Angry Birds, almost no flickering.
I've ordered another MHL adapter.
I returned the third part one and bought the oem Sammy adapter which is now working perfectly without a glitch. I guess these things are really the luck of the draw

I have the adapter that I got with my Infuse. It works almost perfect:
1 - it has to be plugged in after power is applied
2 - It plays perfect on screens and all video players except the vPlayer which uses some different technique to decode/play videos - where it flickers and is un-watchable.
The interesting thing is that on the Note it plays MUCH BETTER than all the other players in HW Mode on some non-standard mp4 files I have.
It does shut down USB while it is connected to HDMI, but goes back on when not just fine.
It would be nice if one could be found that just freeking works!
MHL only works with Samsung released ROM

PROBLEM: No HDMI signal out using MHL adapter cable with USB powered on.
Does work with stock Samsung ROM - All versions.

So basically when I enable HDMI out to my 2560x1440 screen (u2711), the motorola logo displays just fine, but when I select a mode like gallery or mirror, the whole HDMI screen starts flickering and showing portions of the screen every couple of seconds.
The phone itself works just fine, and HDMI out with the same cable works fine on my HD ready TV. The HDMI port on my u2711 is fine as well, at least it works with my xbox 360 in 1080P without error.
The odd thing is, as soon as I enable Picture by Picture on my screen, the phone displays just fine on it's half of the screen, albeit in 640x480.
Is this a known bug, or does anyone have any suggestions on fixing it? Do I have to disable DDC/CI? My cable has ethernet capabilities, so the high res shouldn't be the problem, right? Or did I just buy a ****ty/faulty cable.
I don't think the phone is capable of rendering at a resolution that high, the gallery is in 3D-mode and it's probably running out of Vram..
Maybe force it to 1080p somehow?
I never got the HDMI cable working from my pc high end gfx card to my dell u3011 . Never tried from my Razr but I guess the same applies to it.
Only dual DVI and DisplayPort worked.
Without checking I think the highest res possible on hdmi is 1200p ?
I would always try a different cable before giving up. 9/10 times when I have seen flickering on an HD display it has been a crap/faulty cable, and I have seen it a lot as until recently I was Digital TV installer. Used to carry loads of spare cables in the van as it used to happen so often. You don't have to spend loads on a cable but the very cheapest are usually best steered clear of unless you're lucky. I'd usually go for a £10-£15 cable (15-20 EUR) and not a cheap ebay one.
Thanks for your advice guys!
The max res for 1.4 is 4096×2160, and for 1.3 it's 2560x1600, so my resolution should be fine I think.
I paid ~20 euros for the cable, it's brandless, but from a well known cable retailer here. I don't have any others to test, and compatibility with my u2711 isn't vital to me, so I'm not going to buy another cable, but I still think it's odd that it doesn't work.
I will report back if I find another cable and it makes a difference!
I got my MHL-HDMI cable from Amazon for $10, it's the one listed in the ultimate accessories thread in this forum. It is not working well for me at all, lots of flickering and going blank.
As I understand it, MHL should mean that the phone should be in USB Data/charging mode so it can pass data to the MHL adapter, am I right in assuming this???
If so then the problem may be that the adapter isn't communicating properly with the phone and it's bouncing back and forward between AC Charge and USB mode which would cause all kinds of problems.
Can anyone with a solid, non-flickering MHL adapter check their battery status in 'About Phone>Status>Battery Status' and tell me if it reads AC or USB mode for charging when they are mirroring over MHL HDMI??
Mine reads 'AC charging' and plugging it in I get horrible screen and audio flicker and the screen resolution seems very low. I have the AC power plugged into the MHL adapter and I plug that into the TV first THEN plug it into the phone.
It's pretty much unusable like this, seems like a lot of people are having the same issue with many Samsung phones and tablets.
Anyone resolved this on their note????
Joel
Did a little more testing and noticed something that I think may be odd, wondering if others can confirm.
I checked my battery charge status while plugged into the MHL adaptor and watching the picture flicker on and off on my TV. It read that I was charging in "AC mode". If the phone is in AC mode then surely the data connection to the MHL adapter wouldn't be working and the phone may be pulling too much power away from the adapter for it to work right??
Just wondering if you figured this out. I got the mhl adapter yesterday but the screen flicker makes it unusable.
Figured out that the flicker only happens when wifi is on. When I switch it off its smooth.
Is this the same for you?

I have the ATT Version of the Phone ... and it didndt come with the MHL Adaptor
http://www.google.com/products/cata...=X&ei=zczLT8GLCIOG6QHJhpjtDw&ved=0CJABEPMCMAA
The one I am using is from my older Samsung Infuse - ATT phone also!
I had that working BEFORE with Infuse , and works just as nicely with NOTE
I have the cheapest HDMI v1.4 cable - nothing fancy ( pack of 3 = $5.00 - free ship) ....
The only thing I am P*** about is the in INFUSE - all video's you can load ( 1080p) in mp4 ( borrowed from Itunes etc) with DIRECT TRANSFER ie the infuse didnt go thru any 'conversion' before addin to phone.
In NOTE - the same file - note wants to convert to 'mv' - and in my view = this making it NON 1080p format. Since my NOTE is rooted& unlocked , i can and able to by-pass that conversion C***..
.NOTE = does go into "charge mode' when you stop playing videos/ movies ( I have 64GB sd card ( formated for 32 apps +etc and other 32 GB for movies /videos
Ausmike or anyone else: does your note only charge when using this adapter and not streaming video? mine eats up battery when playing video and streaming and it pisses me off. Why couldn't samsung just used a simple mini HDMI or something similar
Hey all.
I've been running ICS ever since the leak came out (one-click install), and it's been really great. Few bugs here any there but they're mostly small.
I recently received 2 MHL adapters that I bought off of Amazon (one to leave at home, one to shove in my bag for travel) and when testing them out I found that most of the time when I had a screen connected it was just solid black.
I say most of the time because there were a few apps that actually output to the screen (Crayon Physics, built-in camera app, Camera Zoom FX), but just a solid black screen with any other app or on the home screen or in the settings menus.
I tested with both adapters multiple times. Made sure they had power connected to them (used the stock Samsung charger that came with the phone). The HDMI cable is good (used with my computer). Made sure USB degugging was turned off (and when that didn't work also tried it with it on). Since I actually was able to get some output from the adapter I'm assuming the problem wasn't with the adapters themselves.
Is the ICS leak just currently incompatible with MHL adapters? Is there a fix available?
ive had my MHL cable for over 2 weeks now and its got the official samsung logo - and i got it from suntekstore... only problem is i havent got it working...
ive tried with my dads stock 2.3 i9100 on a viewsonic monitor and samsung tv
same with my 4.0.4 i9100 resurrection remix 1.7 + siyah 3.1.2
the other two items i got from suntekstore were 2 OTG adaptors which fail to work... (i also have one that does work from another store) so i think it might be the MHL adaptor itself
yesterday i was frustrated and kept plugging my phone in and out of the samsung tv.... and BAM i got a visual =S after like 10 'no signal' and 2 resolution not supported... but the screen was stuck in portrait... thats the closest ive come to using MHL properly!
on top of that... when i use OTG keyboard connection... the phone freezes if i try pressing caps lock to check for power on my phone! any one else running same OS version and its working?
When successfully connected via MHL the S2 will display in portrait, so that was normal. Apps that run in landscape will do so when run, or where sensor orientation works, like in photo gallery etc, you can rotate it to landscape yourself.
No, as for your issues regarding getting the picture to stay on; first, you did have the Samsung Charger plugged into the MHL cable right, and the correct output channel selected on your tv?
Assuming you did for both the above, the problem is likely with your hdmi cable, not the tv's. Have you tried using different cables? I have a problem with one of my hdmi cables where the screen goes black for a few seconds whenever it pleases, with another cable (which comes with the sky box), it stays on all the time. So try changing cables and see what kind of response you get.
Also, some users have mentioned that they seem to get picture when they put their phones into flight mode first, I've never needed to do this, but give it a go and see what happens. Once you've got your picture up, you can use your tv's remote the control your S2, assumming your tv supports that function.
Hope that helps
I have not tried that rom but last I heard any source based rom doesn't have a working MHL output. I don't know the status at all of OTG on source based roms.
You said you tried it on your dads stock phone but didn't clearly state if it worked or not which it should if the phone is stock. So use that as a basis of if the adaptor is broken.
thanks guys - yeah it could be the hdmi cable... they are pretty cheapo - but on seeing 2 OTG adapters from the same store dont work... the MHL being broken cant really be a coincidence? it was in delivery for over 1 month =[ maybe someone broked it! lol
I think in the end it was the MHL adaptor... ive got a replacement sent out as now the phone wont even recognise power to charge when plugged into the mhl however the charger directly into the phone works! argh may be a long wait for the replacement took 30 days to get my other shipment! may have to resort to a more expensive one
I bought a Viewsonic g tablet on sale a year and a half ago and until this day it meets the light. (It was only touched when purchased then back to the box)
I followed the instructions to the letter (new on this) and everything seems to be working, I have a Malata zpad dock DS-A002 supposed to be fully compatible with the g tablet and I placed the tablet on the dock, connected HDMI in the TV but nothing happens.
Don't see an option in settings to select output to TV.
Many thanks in advance.
Forgot to mention, tried this on the TV which is an LG and monitor which is a Hanns-G
I have to say that this is a first so far. When I read this I went ahead a connected up my dock which is the same make and model as yours to my TV and it works. HDMI is sometimes a pain especially with the newer TV's that are out. You also got to have the dock powered up if you haven't done that. If the power cord is connected and the tablet displays the dock clock then connect the HDMI to the dock with the TV turned off. After connection is made turn on the set and make sure you are on the proper input. It should work, but if not try a different TV.

Thanks for the reply
The LCD TV is a couple of years old, the LCD monitor is 3ish years old
My mother has a 5yr old LCD TV, that's another TV I could test on
The dock is powered up using the charger that came with the gTab
The tablet displays the dock clock when placed on the dock
I've tried different combinations:
Dock powered up, TV off and plugin cable, gtab on then place on dock, turn TV on
Dock powered up, TV off and plugin cable, gtab off then place on dock and power on, turn TV on when gtab is on the dock clock
Dock powered up, TV on and plugin cable, gtab on then place on dock
Dock powered up, TV on and plugin cable, gtab off then place on dock and power on
TV detects HDMI when the gtab is placed on the dock, but after 3-5 secs says no signal meaning it does detect HDMI (shows up as an option, I've tried on all 3 HDMI inputs btw) but it doesn't show up an image.
I've tried these methods in the TV and the monitor, nothing
Doesn't make sense to me since everyone in the thread hasn't had this issue, should be plug-and-play right?

Should I backup the current install and go back to the stock crappy ROM just to test it out? (Wipe everything as instructed before doing so?)
Thanks
No since in going all the way back to stock to test it out. Have you by chance tried a different HDMI cable. You might have a faulty connection or even a dirty connection will make it loose its connection. You may also want to check to see if the TV has a default native setting set. The gtablet will display a image like a PC I believe. Will have to connect it up again to see what res. the device puts out at default.
Alright find the link up solution. I tried different ways of connection all with failure to display on my TV with the exception of this. Try it and you will be satisfied.
1st. Place you dock near your TV with power cord and HDMI cable both connected. Don't connect other end of HDMI cable to TV just yet.
2nd. Have tablet turned on and fully booted up. Then place tablet on dock and leave the dock clock displayed.
3rd. Turn on TV and set the input to the HDMI connection you are about to connect to. Then connect HDMI to that input that is in TV and the display should reflect the device.
Let me know if this works. Thanks.

Hi, yes I tried 2 different cables, different ports, cleaned up (blow air) into the TV and and dock ports (dock is brand new never used from a year+ ago)
I couldn't find a default native setting on the TV.
Really sucks that there is an awesome ROM for the gtablet and I can't use it on the bigger screen, intention was to watch Netflix and movies, besides reading
The tablet is one of those projects that never happened and when I finally manage to get it going this happens...:crying:
Read the addon that I posted. It will connect if you connect it in that order.

Hi Nobe, it still doesn't work. I just don't get it.
TV recognizes the connection (shows as plugged-in) but says no signal.
Unfortunately monitor is not as advanced as a TV, simply says no signal.
Faulty dock? It charges fine
Thanks
Went to stock, and image shows up fine on TV
Is there something I could change, DPI,res? on the current SmoOth install (have backups) that could potentially fix the issue?
Thanks

I keep mine at 160dpi. The issue is that you have to connect everything to the dock before connecting it up to the TV. For some strange reason the dock settings doesn't recognize the connections being made. The dock works fine it is the drivers I believe that are kernel related. If you power up the dock with the HDMI connected to it, then place tablet on the dock, then connect the HDMI to the TV's input with the TV on and turned to that input. Then it should display onto the TV without issues. Done this multiple times when this came up and this was the only way for me to get the dock to display the output of the tablet.

The thing is I did exactly as you said multiple times to be sure.
Using SmoOth image does not come up
Restored to stock ROM and image shows up fine
I'm going to try a fresh SmoOth install and see how it goes or is there any way to check the drivers or make adjustments to it?
Thanks
Any advice on checking the drivers?
Thanks
Actually the drivers are there and working the way they are suppose to be. I do believe that it might in the way it is communicating with the TV still. I am currently working on something that might help out, but I want to test it fully before suggesting it since most everyone doesn't use this feature.

It is really odd that doing the same process on the stock rom works.
Thanks a lot for the follow-up Nobe
Curious if anyone found a solution to this problem? I too have the exact same issue with my Gtab even after trying the solution posted with different cables and such. Stock rom works fine though.
I'm wondering if Nobe found something
